Just perfect...

I am only giving this movie a 1 for the great cast, though I can't imagine what any of them were thinking. This movie was horrible

Your blood may run cold, but you now find yourself pinioned to the story.

It's funny, it's tense, it features two great performances from two actors and the director expertly creates a web of odd tension where you actually don't know what is happening for the majority of the run time.
